PDFKit is a versatile library designed for generating PDF documents in both Node and browser environments, facilitating the creation of intricate, multi-page, printable materials with ease. Its API promotes chainability and offers a combination of low-level functions alongside higher-level abstractions, making it user-friendly. With PDFKit, producing elaborate documents can often be accomplished through just a handful of function calls. It also encompasses access privileges, which include options for printing, copying, modifying, annotating, form filling, ensuring content accessibility, and document assembly. Accessibility features are well-supported, featuring marked content, a logical structure, Tagged PDF, and compliance with PDF/UA standards. Additionally, PDFKit is compatible with JPEG and PNG images, allowing for the use of indexed PNGs and those with transparency. Alongside PDFKit, it's crucial to have a destination to stream the generated output. For projects utilizing PDFKit through Browserify, it's important to install the brfs module via npm, which is essential for loading built-in font data into the library. This combination of features makes PDFKit a powerful tool for anyone looking to create detailed and professional PDF documents efficiently.
